Inventor: KATO TADAHIKO
IPC: B60K17/344
Filed: 1989-10-03
Abstract: PURPOSE:To obtain three positions of two-wheel drive (2WD), rigid four-wheel drive (4WD) and torque split at low cost without any need of a control unit by providing a pair of solenoid valves so controlled as to be turned on and off, and controlling the operation of a shift regulator valve. CONSTITUTION:When a switch 35 is turned to the 2WD position, both of the first and second solenoid valves 33 and 34 are turned on, thereby giving the 2WD position. Also, when the switch 35 is changed over to the 4WD side, both of the aforesaid valves 33 and 34 are turned off, thereby giving the rigid 4WD position. Then, when the switch 35 is changed over to the soft 4WD, the valve 33 is turned of and the other valve 34 turned on, thereby giving a torque split position. Furthermore, when the power is interrupted, both of the aforesaid valves 33 and 34 are turned off and the rigid 4WD position is obtained.

IPC: G11B7/249
Filed: 1984-12-10
Abstract: PURPOSE:To obtain a recording medium having high sensitivity and high resolution, by constituting the recording medium of a monomolecular film or a built-up film thereof of a metal chelate compound isomerized to liberate metal ions or metal atoms when being irradiated with light and a support for the film. CONSTITUTION:The recording medium comprises, for example, a two-layer built-up film of chelate complex molecules consisting of cis-form chelate ligand molecules 1 and metal ions 3 provided on a glass base 4. The medium is immersed in a liquid phase contained in a container 6 having a transparent glass plate 6 as a bottom wall, and is irradiated with trans-form isomerizing light 7 such as UV rays and visible rays in a certain pattern to induce photo- isomerization of formula (I) at the irradiated parts, whereby rearrangement into trans-form chelate ligand molecules takes place, and metal ions 3 are liberated. When the recording medium thus having liberated the ions 3 is taken out and is dried, the reverse isomerization will not occur. Accordingly, the recording medium with information recorded therein can be obtained. The information thus recorded is read by irradiating the medium with light.

Title: Shearing method
Inventor: TANABE YASUSHI
IPC: B21D28/02
Filed: 1994-09-29
Abstract: PURPOSE: To mostly prevent the occurrence of a cracking on a sheared surface of a hard metallic material. CONSTITUTION: By shearing a punched product base stock or a base stock plate itself by the intermittent pressurizing with a metallic die according to the various conditions of the base stock plate, even if the base stock plate is a hard metallic material such as high carbon stainless steel and high carbon steel with low ductility, intermittent and slow shearing becomes possible while extracting positively the ductility of the base stock plate. There is almost nothing to fear the occurrence of cracking on a sheared surface, and a beautiful finished surface can be attained, to which grinding and milling are not necessary. Therefore, even if this manner is applied to a shaving working to a punched product base stock, or applied to the primary punching wording of the base stock plate itself, a remarkable advantage can be provided, which can not be expected from a conventional method.

Title: Traveling speed controller for load carrier
Inventor: WATANABE HARUHIRO
IPC: G05D1/02
Filed: 1992-09-29
Abstract: PURPOSE:To improve operating efficiency and working efficiency or the like by enabling move without shifting load by highly setting target acceleration/ deceleration speed and normal target traveling speed based on the height information of mounted load when the height is low. CONSTITUTION:When the mounted load is moved, a load carrier A receives the address information of the next move target station S at the carrying destination and the detected information of a height detecting means H or the like through a communication equipment CM on the side of the station S and a communication equipment 8 on the side of the load carrier A. The more the height of the mounted load is low, the more the target acceleration/deceleration and the normal traveling speed is heighly set by a controller 9 of the load carrier A based on the detected information of the height detecting means H received from the station S. Then, the controller 9 controls the operation of a motor driving device 10 for traveling so that the detected results of a speed detecting means 15 and an acceleration/deceleration detecting means 16 can be coincident with the set target acceleration/deceleration and normal target traveling speed. Thus, the load carrier can be speedily moved to the destination without shifting the load.

Secondarily, it is treated by plane-degressive processing by using dies 5 so as to be a raw wire material 4 processed into a desired shape. This is introduced to a crucible 2 and made to pass through a molter liquid 6 of conductive material. The silver or silver alloy on the surface of the superconductivity is melted thereby so that one part is mixed with the eluant 6 but the most are infiltrated into hollow holes, etc., in the inside of the superconductivity. A wire material is drawn from the crucible 2 in which the molter liquid 6 is contained so that the conductive material is coated on its surface.  Because the melting point of the conductive material is higher than the silver, the conductive material is solidified at first and then silver, etc., are dispersed in the oxide superconductivity so as to improve critical current density.

IPC: C23C14/40
Filed: 1989-10-06
Abstract: PURPOSE:To remarkably reduce the optical damage of an optical waveguide formed on a ferroelectric crystal substrate by coating the surface of the optical waveguide with a film of a high-transmissivity material which has higher electric conductivity than the optical waveguide in the C-axis direction of the ferroelectric crystal substrate. CONSTITUTION:A high-refractive-index area is formed by thermal diffusion or chemical reaction at a part including the surface of the ferroelectric crystal substrate to form the optical waveguide 2, whose surface is coated with the film of the material which has the higher electric conductivity than the optical waveguide in the C-axis direction of the ferroelectric crystal substrate. Thus, the surface of the optical waveguide 2 is coated by a high-frequency sputtering method, etc., with the film 3 of the material which has the higher electric conductivity than the part of the optical waveguid 2, then charges move through the film 3 so as to cancel a spatial electric field, so that the spatial electric field produced with irradiation light is reduced. Consequently, the refractive index variation (DELTAn) of the part of the optical waveguide 2 decreases and the optical damage is reduced.
